SOLDERING TOOL ATTACHMENT Filed June 27, 1955 2 Sheets-Sheet 2 Inventor Ira Rue/r q v By Attorney Patented Oct. 27, 1936 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to soldering irons and an object of the invention is to provide an improved attachment for the feeding of the solder in wire or ribbon form from a reel on the tool to the head end of the tool so as to flow onto the work directly from the tool, and consists principally in the provision of novel means for advancing the ribbon solder to the point of the tool where it is used, and also in the provision of novel means formounting the solder spool.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view of a soldering tool illustrating the application of the invention.

Figure 2 is a perspective View of a trigger member.

Figure 3 is a detail view taken substantially on the line 3-3 of Figure 2.

Figures 4, 5, and 6 are detail views taken substantially on the lines 4-4, 5-5 and 6-6 respectively of Figure 1.

Figure '7 is a perspective view of a guide 0 member.

Figure 8 is a perspective view of a member provided for preventing retrograde movement of the solder-ribbon as it is being advanced to the point of the tool for use.

Referring to the drawings by reference numerals, it will be seen that It] indicates generally a conventional and somewhat typical type of soldering iron.

In accordance with the present invention there is provided a reel H on which is wound the solder, the same being in the form of a flat strip or ribbon l2.

For supporting the reel I l in operative position on the tool [0 there is provided a frame consisting of a pair of complemental half sections I3--l3 each of which has parallel arms I30, between which the reel is journaled, said arms having the ends thereof pressed inwardly to provide trunnion-teats or bearings M which accommodate the hub of the reel l l in a manner clearly shown in Figure 6 for rotatably supporting the reel in the frame. On the arms l3 are extensions l3b terminating in arcuate clamps or jaws that embrace the barrel Illa of the tool as shown in Figures 1 and 4. The jaws ii are held in clamped engagement with the barrel Illa through the medium of bolts l6 passing through aligned openings in the portions l3b of the frame and provided with springs I! in a manner clearly shown in Figure 4.

, clamp l6 through the medium of the bolt Engaged with the barrel Illa slightly inwardly from the point of the barrel is a two-part clamp l6-l6 whose jaw portions are formed with integral shanks secured together by bolt and nut means ll as best shown in Figure 5. One of said b shanks is slightly longer than the other as indicated at l8, and the free end of the shank extension I8 is pivoted as at If! to a lug provided on a longitudinally curved tubular guide which is preferably formed of aluminum or other suit- 10 able material and through which the solder ribbon or strip L2 is trained as shown in Figure 1 and directed toward the point of the tool as shown in said figure.

The aforementioned reel frame and clamp l0 15 are connected together through the medium of a bar 2lwhich is riveted or otherwise secured at one end to one of the parallel portions l3b of the reel frame and secured at its other end to the A trigger 22 includes a body portion pivoted intermediate its ends as at 23 and at one end is suitably formed to provide a handle 24. locatedconveniently to the handle of the tool l0 so as to be readily manipulated by the thumb of the hand 25 grasping the handle of the tool head. At its other end the body of the trigger 22 is longitudinally twisted as at 25 and in the end 25 thereof is provided with an opening 26 through which is trained the solder ribbon l2. On the side thereof opposite to the reel H the end 25 of the trigger above and below the opening 26 is provided with converging spring fingers 21 that yieldably engage the solder ribbon l2 to advance the ribbon 'toward the point of the tool when the trigger 22 by proper manipulation thereof is caused to rotate about its pivot 23 in a clockwise direction.

A spring 28 secured at one end to the trigger 22 and at an opposite end to the frame !3 normally urges the trigger to rotate in an anti-clockwise direction as Will be clear from a study of Figure 1.

An arm 29 is secured at one end in any suitable manner to the bar 2| and has a twisted end 30 provided with an opening 32 through which the solder ribbon I2 is trained. On one side thereof the end 30 of the bar 29 is provided with spring fingers 33 similar to the aforementioned spring fingers 21 and which engage the solder ribbon l2 in a manner to prevent retrograde movement of the ribbon upon retraction of the trigger 22.

In operation, it is evident that the tool can be held in one hand, and as the solder is used the operator feeds the solder wire forward through the guide 20 by engaging the thumb with the release of the trigger the same will return un action of spring I! to its' normal position w the solder ribbon l2 willbe held in its advanced position by reason of the engagement of the spring fingers 88 with the solder ribbon as thought to be apparent. Thus it will be seen that the tool may be handily used, and in actual practice it is believedthatthesamewillbefoimdtobefreeof numerous objections now raised against the socalled self-feedlng soldering irons as are now known in the art.

Having thus described'the invention, what is claimed as new is:.

An attachment for soldering tools having handles at the rear ends thereof and portions extending forwardly from said handles, comprising a frame adapted to be fixed on and extend laterally from the forwardly extending portion of a soldering tool and having a bar adapted to rest alongside of said forwardly extending portion, a
